Julia 1.8 on Windows fails to handle properly the Git meta credential helper. In .gitconfig:
[credential "helperselector"]
selected = <no helper>
Introduced in Git for Windows v2.23.0.
I wonder if Julia is being tested with this newest Git?
The package manager uses libgit2 for git functionality.
It seems to me that the error originates here:
function split_cfg_entry(ce::ConfigEntry)
key = unsafe_string(ce.name)
# Determine the positions of the delimiters
subsection_delim = something(findfirst(isequal('.'), key), 0)
name_delim = something(findlast(isequal('.'), key), 0)
section = SubString(key, 1, subsection_delim - 1)
subsection = SubString(key, subsection_delim + 1, name_delim - 1)
name = SubString(key, name_delim + 1)
value = unsafe_string(ce.value)
return (section, subsection, name, value)
end
which appears to be pure Julia code. Wouldn’t you agree?
Please post what you did and the error message that resulted.

My .gitconfig:
[credential "helperselector"]
selected = <no helper>
This is created by the “helper selector”, apparently installed with Git.

Reverted the thread subject: the problem is not limited to v1.8.
Would the environment variable JULIA_PKG_USE_CLI_GIT solve this? Then you can just use the git command that comes with Git for Windows?
ENV["JULIA_PKG_USE_CLI_GIT"]=true

Yes, thank you. The code failure is now forestalled. Alas, no credential helper is available still.
I have to type in the username/password for all private repos.
Also, the julia prompt becomes messed up.
